"3-Tier Architecture" Vs. MVC

I don't know if this can be answered in a short space, but when depicting a 3-tier architecture it was always shown with the client, then the business tier in the middle, and the database on the back end.

Now, it seems like when MVC is shown in a diagram it shows the client, then the DATABASE in the middle, with the business tier (I assume) on the back end.

I don't understand the difference (or the advantage) of MVC over the traditional 3-tier. Thanks!

No, the database is not "before" the business layer. You must have seen some poor diagrams.
